The anti-air battery, also commonly referred as the "AAB," is an anti-air defense weapon that is used not only to keep foes away from the cities that they safeguard until the enemies are out of commission, but to also blast ships out of the sky in times of war. These weapons have been known to deal with many threats, such as fighter squadrons, or pirate clans. This structure was designed to put an end to vermin such as those, and in due time. This weapon is not very heavily armed, but packing dual heavy lasers it fires often and accurately, bringing down enemy ships quickly before they can do untold damage to the city.
